Abstract

Appareil de contrôle (10) et méthode de fragmentation progressive d'une pièce à partir de matériau en feuille dans une presse (12) dans laquelle un bélier (28) pénètre progressivement, pas à pas, à travers l'épaisseur de matériau en feuilles, chacun des pas comportant un mouvement d'avance de piston (28) dans la feuille de matériau sur une distance prédéterminée moins l'épaisseur totale de la feuille, un arrêt de l'avance du piston (28), un relâchement de la pression dans la presse (12) à cause de l'avance pressurisée du piston (28) et une avance subséquente du piston (28) à travers la feuille de matériau. Un transducteur de mesure de distance (48) génère une sortie indiquant la position du piston (24) du cylindre (14) et du bélier (28) durant le mouvement du bélier. Un contrôleur (34), en réaction aux commandes d'un logiciel en mémoire et à la sortie du transducteur de mesure de distance (48) commande le fonctionnement de robinets de fluide (57, 62) afin d'alimenter le cylindre (14) en fluide sous pression pour imprimer au bélier (28) un mouvement de va et vient. Le contrôleur (34) commande les soupapes de régulation de pression (114, 116, 118, 120, 122) afin d'alimenter le cylindre (14) en fluide à une pluralité de pressions discrètes, à chaque cycle de fonctionnement de la presse (12).
